After putting this together and trying it out, I heard cracks and pops all the way down my neck and spine right away, so it does what I bought it for and feels stable enough to hold my weight and be simple to use. Word of caution: if you set the leg pads close to the middle so that the adjustment pole is sticking out, dismount carefully! Neglecting to swing your leg over that adjustment pole will result in some ugly bruises on the inside of your thigh.
